Assessment: WAEC SSCE - General Mathematics - 2017 (Objective) Subject: General Mathematics

Question 1 Report

If P(2,3) and Q)2, 5) are points on a graph, calculate the length PQ

Answer Details
To calculate the length of PQ, we need to use the distance formula, which is: distance = square root of [(x2 - x1)^2 + (y2 - y1)^2] Here, P is at (2,3) and Q is at (2,5). So, x1=2, y1=3, x2=2, and y2=5. Plugging these values into the formula, we get: distance = square root of [(2 - 2)^2 + (5 - 3)^2] distance = square root of [0 + 4] distance = square root of 4 distance = 2 Therefore, the length of PQ is 2 units.
